The second rotor is disposed to be rotatable with and relative to the first rotor. The centrifugal element is disposed within the accommodation portion. The centrifugal element is disposed to be radially movable by a centrifugal force acting thereon in rotation of the first or second rotor. The centrifugal element rotates about a rotational axis thereof in radial movement thereof. The first rolling member is disposed between the first guide surface and the centrifugal element. The first rolling member rolls on the first guide surface in accordance with rotation of the centrifugal element about the rotational axis thereof.
